Is the population here an accurate representation of religious opinion in the US?

As a humanist, I am scared... nay, petrified about the current state of affairs in this country regarding religion. After having been on Yahoo! Answers this long, I am truly saddened by the amount of willful ignorance, irrational thought, and absurd beliefs I have seen represented in this section. Is critical thought on the decline or on the rise? Are there other atheists/freethinkers/humanists that share my concern?
